Pacific Rubiales announces approval of a patent grant for its proprietary STAR technology, in Colombia

October 1, 2013

TORONTO, Oct. 1, 2013 /PRNewswire/ – Pacific Rubiales Energy Corp. (TSX: PRE;
BVC: PREC; BOVESPA: PREB) is pleased to announce that it has been
granted a patent for its proprietary Synchronized Thermal Additional
Recovery (“STAR“) enhanced oil recovery technology by the Colombian patent authority,
the Superintendencia de Industria y Comercio (“SIC”).

The patent award by the SIC provides the Company with intellectual
property rights to the STAR technology in Colombia for an exclusive 20
year period from the filing date of April 1, 2011, to April 1, 2031.
The patent specifically recognizes: 1) the synchronized system of oil
production using the combustion process, employing in-situ measurement,
monitoring and control of operational conditions in real time and
distance, and 2) the use of a numerical model intelligent
well/subsurface system to monitor and control the progress of the
combustion front and fluids; critical to successful application of

Ronald Pantin, Chief Executive Officer of the Company, commented:

“This patent represents a strong endorsement and provides additional
credibility to STAR by recognizing the importance of this technology
and the value we expect it to bring to both Pacific Rubiales
shareholders and to Colombia.

“Recently we announced that early progress in our Quifa SW field STAR
pilot project had indicated that the technology had already resulted in
a doubling of the recovery factor, in one of the largest producing
heavy oil fields in Colombia. On the back of the independent
certification of these results by three independent engineering firms,
the Company is progressing with plans to expand the STAR pilot to first
commercial application in Quifa SW in 2014.

“Pacific Rubiales is a demonstrated first mover and leader in heavy oil
exploration and production in Colombia. We believe that the success of
STAR has important implications beyond the Quifa SW field because more
than 75% of Colombia’s total oil production growth since 2004 has come
from heavy oil, with the majority of that coming from the Company
operated Rubiales and Quifa fields, currently producing under primary
recovery flow methods only.

“With very large volumes of Original Oil in Place in a number of
discovered fields, heavy oil production is as much the future of the
Colombian oil industry, as it is the future of Pacific Rubiales. The
granting of this patent recognizes the commercial value and future of
STAR, and the Company’s pioneering role in its development.”

Superintendencia de Industria y Comercio (SIC) is a competitiveness
regulatory agency of the Government of Colombia in charge of regulating
fair business practices, promoting competitiveness and acting as the
Colombian patent and registration office.

Pacific Rubiales, a Canadian company and producer of natural gas and
crude oil, owns 100% of Meta Petroleum Corp., which operates the
Rubiales, Piriri and Quifa heavy oil fields in the Llanos Basin, and
100% of Pacific Stratus Energy Colombia Corp., which operates the La
Creciente natural gas field in the northwestern area of Colombia. 
Pacific Rubiales has also acquired 100% of PetroMagdalena Energy Corp.,
which owns light oil assets in Colombia, and 100% of C&C Energia Ltd.,
which owns light oil assets in the Llanos Basin.  In addition, the
Company has a diversified portfolio of assets beyond Colombia, which
includes producing and exploration assets in Peru, Guatemala, Brazil,
Guyana and Papua New Guinea.

The Company’s common shares trade on the Toronto Stock Exchange and La
Bolsa de Valores de Colombia and as Brazilian Depositary Receipts on
Brazil’s Bolsa de Valores Mercadorias e Futuros under the ticker
